Description
Technical field
The present invention relates to heat treatment die technical field, specifically a kind of Pressure quenching mould of locomotive traction gear ring.
Background technology
In order to obtain preferable fatigue resistance, the final of gear ring is drawn as railway locomotive frequently with carburizing and quenching at present
Technology for Heating Processing.In actual processing, the carburizing and quenching deformation of circle type gear is larger, common are ellipse, taper, end face run-out etc.
Distortion type, gear ring distortion causes following process not have surplus, and teeth portion effective case depth is uneven, reduces product quality.
The reason for causing circle type gear to deform is complex, mainly has raw material, part shape, mach processing capacity and adds hot and cold
But technique etc., these factors influence each other so that control gear ring distortion seems particularly difficult.
Control method in the prior art to circle type gear carburizing and quenching distortion is less, and Main Means are to increase carburizing and quenching
Front gear allowance, allowance and raw material and shape have substantial connection, and it controls difficulty big, it is not easy to reach ideal
Surplus, and excessive allowance can cause the decline of teeth portion hardness and intensity, also, because tooth root position is without grinding
Processing, teeth portion stock removal is excessive, can make to form grinding boss at tooth root, too small allowance can not then reduce gear ring distortion,
Both product rejection is easily caused.
Cause the factor of gear ring deformation numerous, and require to formulate unified processing for different material, shape, process technology
Method controls gear ring deformation to be unpractical, and more possible means are to provide a kind of carburizing and quenching equipment, improve quenching apparatus
